Telomere length in leukocytes and cervical smears of women with high-risk human papillomavirus (HR HPV) infection
2019
Objective: Persistent high-risk HPV (HR HPV) infection leads to the development of squamous intraepithelial lesions, which in turn may progress to cervical cancer. Telomere elongation or shortening may indicate a carcinogenesis process. In the present study, we analyzed telomere length from blood and cervical smears of women without and with high-risk HPV infection. Materials and methods: Telomere length was quantified by real-time PCR in blood and cervical smears from 48 women with high-risk HPV infection and HGSIL or LGSIL, 29 women HR-HPV positive without SIL, and 11 HPV-negative women. Results: No correlation was found between age and telomere length in blood and cervical smears. Women …
Reproductive and Hormonal Factors, and Ovarian Cancer Risk for BRCA1 and BRCA2 Mutation Carriers: Results from the International BRCA1/2 Carrier Coho…
2009
Abstract Background: Several reproductive and hormonal factors are known to be associated with ovarian cancer risk in the general population, including parity and oral contraceptive (OC) use. However, their effect on ovarian cancer risk for BRCA1 and BRCA2 mutation carriers has only been investigated in a small number of studies. Methods: We used data on 2,281 BRCA1 carriers and 1,038 BRCA2 carriers from the International BRCA1/2 Carrier Cohort Study to evaluate the effect of reproductive and hormonal factors on ovarian cancer risk for mutation carriers. Data were analyzed within a weighted Cox proportional hazards framework. Results: There were no significant differences in the risk of ova…
Proliferative verrucous vs conventional leukoplakia: no significantly increased risk of HPV infection
2004
Proliferative verrucous leukoplakia (PVL) is a very aggressive form of oral leukoplakia (OL) with high morbidity and mortality rates, hypothesised to be linked to HPV infection. This study aimed to determine the presence of HPV DNA in PVL in comparison with OL, and in relation to social-demographical variables (age, gender, smoking and drinking habits) in an Italian multi-centric hospital-based study. The study group consisted of 58 cases of PVL and 90 cases of OL as controls (47 homogeneous (H) and 43 non-homogeneous (non-H) form), both recruited from four Italian cohorts. HPV DNA was identified in exfoliated mucosal cells by nested PCR (nPCR) with MY09/MY11 and GP5+/GP6+ primer pairs and …
Concentrations of inhibins and activin in women undergoing stimulation with recombinant follicle-stimulating hormone for in vitro fertilization treat…
2001
To investigate the influence of human recombinant follicle-stimulating hormone (FSH) on circulating serum concentrations of the ovarian proteohormones inhibin A, inhibin B, pro alpha-C, and activin A and serum levels of estradiol after down-regulation with GnRH analogue.Serum concentrations of ovarian proteohormones and estradiol.Academic clinical practice.30 women who underwent assisted reproductive techniques.Blood samples were analyzed for inhibin A, inhibin B, pro alpha-C, activin A, and estradiol during IVF treatment at points coinciding with pituitary down-regulation, stimulation with recombinant FSH, ovulatory triggering, and the luteal phase of the cycle.Activin A levels did not cha…
Milder forms of atherogenic dyslipidemia in ovulatory versus anovulatory polycystic ovary syndrome phenotype
2017
BACKGROUND: Dyslipidemia is common in women with polycystic ovary syndrome (PCOS) but its prevalence in different PCOS phenotypes is still largely unknown. METHODS: We measured plasma lipids and lipoproteins in 35 anovulatory PCOS (age: 25 ± 6 years, BMI: 28 ± 6 kg/m2), 15 ovulatory PCOS (age: 30 ± 6 years, BMI: 25 ± 3 kg/m2) and 27 healthy women (controls) age- and BMI-matched with ovulatory PCOS. PCOS was diagnosed by the presence of clinical or biologic hyperandrogenism associated with chronic anovulation and/or polycystic ovaries at ultrasound. In women with normal menses chronic anovulation was indicated by low serum progesterone levels (<9.54 nmol/l) during midluteal phase (days 21…
Does ovarian blood flow distinguish between ovulatory and anovulatory patients with polycystic ovary syndrome?
2003
The purpose of this study was to determine whether parameters of ovarian blood flow distinguish between women with polycystic ovary syndrome (PCOS) who ovulate and those who are anovulatory.This was a prospectively enrolled trial, carried out as a cross-sectional comparison of 12 ovulatory patients with PCOS and 20 matched subjects with classic PCOS and 10 healthy control subjects. Hormonal parameters and ovarian blood flow by color flow Doppler imaging were obtained in the early follicular phase.Characteristic elevations in luteinizing hormone (LH) and androgens were found in both groups with PCOS compared with control groups. Women with anovulatory PCOS had high insulin levels and lower Q…
Clinical and endocrine characteristics of the main polycystic ovary syndrome phenotypes
2009
Abstract OBJECTIVE: To evaluate the clinical and endocrine differences between main polycystic ovary syndrome (PCOS) phenotypes. DESIGN: To evaluate clinical and hormone parameters in a large group of consecutive women with PCOS diagnosed according Rotterdam criteria and divided according their phenotype. SETTING: University department of medicine. PATIENT(S): Three hundred eighty-two consecutive women with PCOS and 85 ovulatory controls. INTERVENTION(S): Evaluation of clinical and hormone parameters. MAIN OUTCOME MEASURE(S): Blood levels of gonadotropins, testosterone, sex-hormone-binding globulin, dehydroepiandrosterone sulfate, 17α-hydroxyprogesterone, progesterone, glucose, and insulin,…
Perinatal and newborn care in a two years retrospective study in a first level peripheral hospital in Sicily (Italy)
2019
Abstract Background Two hundred seventy-five thousand maternal deaths, 2.7 million neonatal deaths, and 2.6 million stillbirths have been estimated in 2015 worldwide, almost all in low-income countries (LICs). Moreover, more than 20 million severe disabilities result from the complications of pregnancy, childbirth or its management each year. A significant decrease of mortality/morbidity rates could be achieved by providing effective perinatal and newborn care also in high-income countries (HICs), especially in peripheral hospitals and/or rural areas, where the number of childbirths per year is often under the minimal threshold recognized by the reference legislation. We report on a 2 years…
Presentation and Outcomes of Pregnancy in Patients With Autoimmune Hepatitis
2018
Autoimmune hepatitis (AIH) frequently affects women of childbearing age in whom the desire to have a family raises the question regarding the potential risks for the fetus and the mother. The information on AIH in pregnant patients is scarce.1 The aims of this study were (1) to identify the risk factors associated with flares in pregnant patients diagnosed with AIH, (2) to determine the course of AIH in patients with pregnancy-related flares, and (3) to describe the outcome of AIH diagnosed in the postpartum period.
Ramadan fasting and newborn's birth weight in pregnant Muslim women in The Netherlands.
2014
Many Muslim women worldwide are pregnant during Ramadan and adhere to Ramadan fasting during pregnancy. In the present study, we determined whether maternal adherence to Ramadan fasting during pregnancy has an impact on the birth weight of the newborn, and whether the effects differed according to trimester in which Ramadan fasting took place. A prospective cohort study was conducted in 130 pregnant Muslim women who attended antenatal care in Amsterdam and Zaanstad, The Netherlands. Data on adherence to Ramadan fasting during pregnancy and demographics were self-reported by pregnant women, and the outcome of the newborn was retrieved from medical records after delivery. The results showed t…
